Backup and Recovery

DST has documented policies and procedures that exist for backup, recovery and off-

site storage of backup.

Winchester Data Center performs both daily incremental and weekly full backups of

TA2000 application and client data, as well as non-TA2000 client data, including

Mainframe operating system data. The data is first sent from Winchester to the DST

Recovery Center. A tape is automatically created by the DR VTS (Disaster Recovery

Virtual Tape System) at the DST Recovery Center. An additional copy of data is sent

from Winchester to the AWD Data Center where a second tape is created. All system

data backups are scheduled through the enterprise job scheduling solution, ESP.

DST also has a mirroring process in place that allows TA2000 application and client

data to be backed up in a peer-to-peer manner. A real-time copy is sent from the

Winchester Data Center to the DST Recovery Center through fiber optic links when a

"write" command occurs on the TA2000 platforms.

UNIX servers, located at Winchester, are backed up to tape daily. A full system

backup is performed when a server is first placed in production. After that, daily

incremental backups are performed. Two copies of backups are made to tape. The first

copy is created at Winchester and stored onsite. Backup data is then transmitted to the

DST Recovery Center where a secondary tape copy is created and retained.

Windows servers are backed up to tape daily. A full system backup is performed when

a server is first placed into production. After that, daily incremental backups are

performed. Two copies of backups are made to tape. The first copy is created at the

server‟s data center and stored onsite. Backup data is then transmitted to the other data

center where a second tape copy is created and retained. Management reviews a report

daily to ensure backups are performed successfully for all Windows servers.

The iSeries systems reside in both the AWD Data Center and Winchester Data Center

and are monitored by the AWD Data Center Operations Team. Backups for the iSeries

environment consist of a two-layer process during which the data is first mirrored to

the other data center in real-time and second, the data is backed up to tape from the

mirrored data. Should disaster recovery be necessary, the mirroring process allows

DST to switch clients from the AWD Data Center to Winchester and vice versa. In

addition to the mirroring process, full backups of iSeries data to tape are performed

daily and a full system backup is performed weekly.

System backups are scheduled, monitored and logged by the scheduled shift manager

and computer operators at both data centers. In the event that there are errors or

problems with the backups, appropriate escalation procedures are in place to resolve

the issue.
